From the Web Telescope discovering a new galaxy to following the controversy surrounding scientist Ranga Dias, find the latest and most exciting updates from the field of science here.
JWST Discovers New Quiescent Galaxy
Using the James Webb Telescope, astronomers discovered a quiet galaxy named JADES-GS+53.15508-27.80178. The galaxy is relatively low in mass and shows little sign of star formation. Formed when the universe was only 700 million years old, the galaxy has a high redshift that can give astronomers insight into the early days of the universe. After the starburst the galaxy appears to be compact and disc-shaped with a radius of 650 light years.
NASA hands over NISAR satellite to ISRO
The Indian Space Research Organization (ISRO) has received the NASA-ISRO SAR (NISAR) satellite from the US space agency. NISAR is a low earth orbit observatory jointly developed by NASA and ISRO. The satellite will map the entire Earth within 12 days and provide spatially and temporally consistent data to understand Earth’s ecosystems, ice mass, vegetation biomass, sea level rise, groundwater and natural hazards, including earthquakes, tsunamis, volcanoes and landslides.
La Niña, which makes droughts and hurricanes worse, is gone
Three bad years later, La Niña weather events that increased Atlantic hurricane activity and worsened the drought in the West. That’s generally good news for the United States and other parts of the world, including drought-stricken northeast Africa, scientists said. Earth is now considered to be in a “neutral” state and is likely trending toward El Niño in late summer or fall.
Global food system emissions damaging Paris climate targets
Greenhouse gas emissions from the global food system will add nearly one degree Celsius to Earth’s surface temperature by 2100 at current trends, obliterating Paris Agreement climate goals, scientists have warned. A major shift in sectors—from production to distribution to consumption—could cut these emissions by more than half as the world population grows. The global food system is responsible for about 15% of current warming.
IISc study says antibiotic drugs given to cattle cuts carbon in soil and affects climate
Researchers at the Center for Ecological Sciences (CES), Indian Institute of Science (IISC) have found that cattle grazing stores less carbon in the soil than grazing by wild herbivores. In a study conducted in the Spiti region of the Himalayas, CES researchers found that this difference was due to the use of veterinary antibiotics such as tetracycline on animals.
World’s fastest single-shot camera confirms how flames form glass
Scientists in Germany and the US have developed the world’s fastest single-shot laser camera – 1,000x faster than its predecessors in capturing extremely short-lived events. They used cameras to provide the most precise view yet of how hydrocarbon flames form soot, which could teach us about how this important climate pollutant is produced in kitchen stoves, car engines and wildfires.
Scientists who reported room-temperature superconductivity faced further controversy
March 9, Journal of Physics Physical review letter (PRL) launched an investigation in June 2021 after allegations of data manipulation, co-authored by Ranga Dias, the same week that Dias and others reported in a different journal that they had discovered room-temperature superconductivity. A material compressed by several thousand atmospheres of pressure. Now, Dias et al. reported that nitrogen-doped lutetium hydride becomes superconducting at 21° C and 20,000 atmospheres (atm).
Unraveling the secrets of bee dance language
New research shows that the bee’s wagging dance acts as a form of communication, both an innate and learned behavior. They can tell each other where to find resources such as food, water or shelter through a physical “waggle dance”. This dance communicates the direction, distance, and quality of the resource to the bees. Studies have shown that younger bees learned parts of the waggle from older nestlings.
